Tire Pressure Monitor Failure - Again

edited November -1 in Roadster
Has anybody managed to fix the tire pressure monitor as a DIY project?
I've got a Roadster 2.5

Since this has failed on me three times in four years, and is now out of Warranty, I don't look forward to taking the car 50+ miles and paying the service center rates every 15 months.

Actually, if you include all the other things that break every 15 months, I'm taking this it in several times a year. More so than my Toyota or Acura. Under normal conditions, this would qualify under some states "automotive lemon law".

I am supposed to show off the car in two days at National Drive Electric Week. Now I get to show it off with fault lights all over the dashboard. Nice huh?

Anyway... end of rant.

If anyone can steer me toward a more effective solution, it would be appreciated.

    Well, I have to assume that there is no alternative than continue to put low quality parts in, and pay to have them swapped out every 15-20 months.

    As someone told me, maybe they can just spend $50 for a better component, and not have to replace it every year and a half!

    I would think that Tesla would be concerned about how they are perceived. Three people who really thought the Tesla design is cool are now turned off after seeing how many times I've had to fix things. One of them is my company VP, seeing the loaner cars and laughs when he says, "You spent how much for that thing?? and they keep having to fix stuff how many times?".

    Maybe I'll just watch the "Fault" messages keep piling up.

    Here is a followup to any who may search, and find this.
    They diagnostic logs I read said the Monitor system had failed. However, the service shop told me only one of the tire sensors were bad. This was the second, the first had failed in less than a year.

    I don't know why the entire system refused to function when only one of the tires was not sensing... But that is the way they say it works.

    It has been reported that the sensors are battery powered, but I cannot confirm that. They are supposed to have a life of 4-5 years.

    So, based on this, I had them replace all four sensors, since three were over 4 years old, and one was slightly less than four years old.

    I recently had tires replaced on Roadster at Discount Tires.
    As work was being preformed the tech, a very knowledgeable tech., offered to check and replace the TPMS om each tire at a reasonable price.
    Discount tire tech indicated parts did not have to be Tesla authorized parts, most TPMS parts are manufactured by same co.
    I did not have a problem with TPMS on my Roadster, so I declined.
    I replaced the rear tires with Michelin Pilot Super Sports( @ $135. ea. with 15K mile warranty) and the handling and quietness is unbelievably better than the Yoko's .Yoko's on front.
    Same tire Tesla is putting on the Model X, Michelin Pilot SS.

    Thanks. I use Discount Tire for everything. I have 45K tires on the rear, but got about 12K out of them, and they gave me good credit.

    The fronts I just replaced at 25K, and they could only come up with the same as the originals. Much more expensive.

    Not knowing what the sensor manufacturers were, I didn't know if I had to have them match the receiver unit. I probably could have gotten it done for a few dollars each, and installed free since they do everything for me, and I have lifetime balancing and rotation.

    Hi Scott,
    I received a phone call from a Tesla Rep. the afternoon of the 12th, her name is Laura , phone # 1-510-896-6412, super nice person. She is performing a survey on the 3.0 Roadster Battery upgrade and wishes to hear from as many Roadster owners as possible,either she will call U if U as a Roadster owner is on her list or she is OK with us calling her, so posting her phone # is OK.
    She is compiling opinions on the upgrade as well as concerns in general,that Roadster owners have in other areas, which she is passing on to Tesla. I expressed my concerns on not having HPC 70 AMP charging connections at the Supercharger stations for the Roadster owners who travel beyond their city limits.
    Scotty, I mention U to her and UR concern on the TPMS problems U are having,plus the fact that U cannot travel from Dallas to San Antonio to visit relatives, not having a way to charge in order to get back to Dallas.Maybe U could elaborate on this subject.
    My example of "Range Anxiety" to her was not being able to travel from Houston to Dallas or Austin without a 70AMP charging connection at the Supercharger stations along the way, therefore a typical 3.5 to 4 hour trip would take 8 hours using a Level 2 public charging system.
    So the message is to all Roadster owners who may read this forum comment, call Laura and offer UR opinion on UR Roadster experience good or negative, she is Tesla ears to a better tomorrow for us.

    We're veering off topic but I can't fathom Tesla is going to spend money upgrading the Supercharger stations for 1,500 vehicles when they were designed for the hundreds of thousands of newer models. They have said they aren't making a red cent on the 3.0 battery upgrade and offering it as goodwill to their first customers. Upgrading Superchargers will never happen.
